Answer:
y = -2(x + 1)
Step-by-step explanation:
x-intercept of -1 means y=0 when x=-1, so you have your (x₁, y₁) value of (-1, 0).
Slope is -2 so m=-2.
Plug into point-slope formula:
y = m(x - x₁) + y₁
y = (-2)(x - (-1)) + (0)
y = -2(x + 1)
Yes, all your answers are correct!
Step-by-step explanation:
DC is equal to 180°, so subtract 105 from 180.
180-105=75
180 is the total of the the angles when added together.
67°+75°=142
180-142=38
x=38
The answer is 31115.
27% of 24500 is 6615 so adding them together would result in 31115
